3 Claims.

This invention relates to a machine for filling casings of pillows and similar containers, with fibrous material such as kapok, cotton, etc.

An object of this invention is to provide a filling machine comprising a cylindrical casing having perforations through the major portion of its periphery and having suction means for removing the air through the perforated periphery of the casing and from filling material within the casing, to permit filling non-porous pillow casings, etc.

Another object of this invention is to provide suction means connected with a' suction chamber fixed around the outer circumference of the perforated portion 'of the casing through which the air surrounding the fibrous material in the casing is removed while a feeding action takes place on the fibrous material.

Another object of this inventio n is to provide a perforated hollow drum rotatably mounted within the perforated casing, the drum having a plurality of ejecting feeder arms extending to the inner periphery of the casing, and the drum having one side wall open and in communication with a suction pipe at the center of the casing to provide a coacting relationship between the air at the inner and outer portions of the casing caused by a pre-determined regulated suction.

Another object of this invention resides in the utilization of regulating dampers in pipes leading from the suction chambers. The dampers may be separately opened and closed to provide a regulated amount of suction from inside the perforated drum and from outside the perforated casing simultaneously.

The regulated suction functions to overcome the air pressure created by the revolving impeller blades in the impeller chamber so that the resultant tendency for air flow in the nozzl is substantially zero, that is neither outward nor inward.

This facilitates the ejection of air-free material from the filling machine into the nonporous casing to be filled.

With the above and other objects in View, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawings and pointed out in the claims which form part of this specification.

Reference will now be had to the drawings, wherein like numerals of reference. designate corresponding parts throughout the several views, in which:

Figure l is a. front elevation of the filling ma- 2 chine, partly broken away to show the interior thereof.

Figure 2 is a cross-sectional View, the section being taken as on line 2-2 in'Figure 1.

Figure 3 is a top plan View ofthe filling ma.-

In the illustrated embodiment of the invention the numeral it indicates a filling machine for filling containers such as cushions, pillows, etc., with fibrous filling material, such as kapok, cotton, etc. g 1

The filling'machine l6 comprises a casing II which is of cylindrical fform. 'Rotatably' mount-* ed in a bearing 42 which is secured to aside wall is of the casing ii is a s aft 16. The shaft extends into the casing i band has a flange l5 suitably secured thereto inside the casing.

A drum 15 has a solid wall I! and issecured V to the flange l5 by rivets it.

The drum i6 has an open side 20. i

For the purpose of this invention, the drum by a motor 21 is in communication with the interior of the drum H5 by means of a pipe 28. A circular suction chamber 29 is suitably secured around the casing H. The chamber 29 extends sufficiently around the casing to cover the perforated portion of the casing.

The suction means 26 is also in communication with'the suction chamber 29 by means of a pipe 30.

Impeller blades 3| are secured centrally or diametrically of the drum IS. The blades 3| terminate close to the inner surface of the casing H and when rotated exert a feeding action on filling material in the casing due to the momentum imparted to the filling material by the centrifugal force.

It is to be noted that the filling material when deposited in the hopper 22 is fed by the impeller blades Iii-into and through the nozzle 23 into a container 32 suitably held on the nozzle. The air displaced from the container 32 is removed by the suction means 26.

As shown in Figure 1, a disk valve or damper 35 is mounted in a branch 28' of the pipe 28 on a pin 36 passing diametrically through the butterfly or disk valve 35. The valve 35 may be perforated drum or central suction chamber l6.

The suction chamber 29 is divided by a partition 31 into branch suction chambers 29 29 The pipe 30 has branch inlets 3B, 39. Butterfly or disk valves 40, 4| in the inlets 38, 39 are similar to the valve 35 and provide a, regulated amount of suction in the branch suction chambers 29 and 29 The advantage of dividing the suction chamber into two suction chambers 29' and 29 is that if only one chamber and one valve were used at the middle of the chamber, the valve would tend to clog up and be ineffective. The arrangement shown avoids the formation of a neutral point where there is no or very low air velocity to carry dust. It would clog.

In operation, the shaft I4 is rotated 45' from any suitable power source.

by a pulley The operator feeds the fibrous material into the hopper 22 while the suction means 26 exerts a suction on the material from opposite sides of the impeller chamber 45. This suction neutralizes the air pressure created by the high speed revolving blades 3|. The blades 3| feed the air-free material into and through the nozzle 23 into nonporous casings 32.

In accordance with the patent statutes I have described and iillustrated the preferred embodiment of my invention, but it will be understood that various changes and modifications can be made therein without departing from the spirit of the inventionas defined by the appended claims.

Iclaim:

lfIn a filling machine for filling containers with air-free fibrous material, comprising a perforated cylindrical casings, perforateddrum rotatably mounted in said casing and having arms diametrically disposed therein, said casing having having a hopper in one side wall and a nozzle in tangential relation therewith, a suction chamber fixedly secured around the outer periphery of said casing, suction means in communication with said suction chamber, and with said filling material in said casing through said perfora- 4 tions, whereby fibrous material having interstices between the fibers and deposited in said hopper is fed to said arms between said perforated drum and said perforated casing and is fed by said arms into and through said nozzle while the entrained air is removed from said filling material through said interstices from opposite sides of said material.

2. In a filling machine for filling non-porous containers with air-free fibrous material, comprising a casing having perforations through a portion of its periphery, a perforated drum rotatably mounted in said casing and having impelling feeder arms carried thereby, said casing having a hopper and a nozzle in tangential relation with the periphery thereof, a suction chamber fixedly secured in circumscribing relation with the outer periphery of the perforated portion of said casing, suction means in communication with said circumscribing suction chamber, said suction means being also in communication with the interior of said drum or central suction chamber, and with said filling material in said casing through said perforations in said casing and in said drum, whereby fibrous material deposited in said hopper is fed to said arm between said perforated drum and said perforated casing and is accelerated and ejected by said arms airfree through said nozzle into said container.

3. The invention as defined in claim 2, wherein means is provided for regulating the suction in said central and in said circumscribing suction chambers, to cause a regualted suction on said filling material.
